Abstract

A common cause of malfunction on cooling units is refrigerant leakage. Its diagnosis is done by technician during regular maintenance or, after most of the refrigerant has leaked. An indirect leak detection method on cooling units based on comparison of data for the critical operating parameters and their optimum values with the values measured. A device integrated in cooling units, applying the above method, measuring and monitoring the condensing and evaporating pressures and temperatures using sensors and comparing them with the optimal, according to an algorithm, can diagnose refrigerant leaks. A stand alone testing and diagnosing device applying the above method with upgraded open algorithm accepting variables input for the unit tested, that includes quick couplers to hook up to cooling units can reduce the diagnostic errors.
